Although Arkansas quarterback Ryan Mallett refused to address questions from the media about alleged drug use at the NFL Scouting Combine in Indianapolis -- after dodging several queries, Mallett abruptly ended his press conference -- he apparently came clean in interviews with NFL teams.

"One G.M. said Mallett was the first quarterback ever to admit his drug usage to him in interviews, and his willingness to be honest about his past and acknowledge issues is viewed as a positive," according to Pro Football Weekly. "Concerns about his history of use could impact his draft position, though."

Ryan Mallett reportedly has discussed past drug usage with NFL teams. Some teams view this as a positive.

Auburn's Cam Newton and Missouri's Blaine Gabbert are the only two quarterbacks considered top 10 picks in this year's draft. Mallett is generally considered to be in the next tier, along with Washington's Jake Locker, Florida State's Christian Ponder, TCU's Andy Dalton and Nevada's Colin Kaepernick.

In addition to the drug rumors -- Mallett reportedly never tested positive at Arkansas -- his character was sullied by an arrest for public intoxication. Some NFL teams are concerned about Mallett's reputation as a "big party guy," according to PFW.

On the field, NFL talent evaluators have questioned Mallett's decision-making.
